Less than a hundred years ago, there was serious debate among professional astronomers about whether our Milky Way galaxy, with its many billions of stars, was the entire universe. By the end of the 1920s, Edwin Hubble, a New Albany, Ind., high school teacher and basketball coach who left teaching to become a professional astronomer, convincingly demonstrated that our galaxy was one of many. In doing so, he changed humanity's view of our place in the universe. Again. Scientists now estimate that there are many billions of galaxies beyond our own Milky Way.
